Summary: Cheerleading
for the "Panthers" sets us in an affluent high school.
Michael fights Billy over Tammy; gay black friend Byron looks on. We cut
to Dr. Wachenstein testing his mechanical T-Rex model (why is it smoky?)
and wanting to proceed beyond the "limitations of that stupid
computer."

Michael sneaks into Tammy's room, but schoolchicks
rat him out to Billy, who attacks with his gang and leaves Michael
in the local suburban wild animal park where lions run loose.
Billy asks him, irrelevantly, "What would you do if you had
the power to do anything?" In any case, a male lion chases
and mauls Michael before a game warden can shoot the animal. Michael
remains comatose in the hospital, watched over by a drunken Uncle
Bob, his only relative. Dr. Wachenstein and his assistant Helga
intrude and declare Michael dead in order to steal his brain and
hook it up to the T-Rex.

The T-Rex with Michael's brain sees Michael's
body and then itself in a mirror. It stomps Karl, another assistant,
and tries to phone Tammy, and terrorizes drunks. Tammy is weepy
but at a party, and when the dino hides in the trees, Billy's
friend urinates on its leg and gets killed. The dino terrorizes
the crowd, but lets Byron go. The cops afterwards eat disgustingly
at the scene of the massacre and laugh about gutting deer.

Helga rolls up a flattened Karl. Tammy disappears
out the window after the T-Rex shows up and, in a barn, is made
to realize about the dinosaur: "You have Michael's brain?"

Dr. Wachenstein later views Tammy as bait to
retrieve the dinosaur, but Tammy and Byron plan to retrieve Michael's
body after the funeral. The T-Rex cries at Uncle Bob's eulogy.
Unfortunately, the body is gross and rats are involved, so after
an attempted kidnapping by the Doctor and Helga, Tammy and Byron
try to find a body that will suit Michael's brain. With the scientists
tied up and the T-Rex in a truck, they display their findings
at the local morgue. ("They're all old over here." "Dead
is as old as you're gonna get, honey.")

After a chase sequence, the three are trapped
in a barn. Dr. Wachenstein wants to tranquilize the dinosaur,
which he nevertheless claims is merely mechanical. The T-Rex is
able to kill the Doctor, but the cops open fire and kill it.

We cut to a happy home scene. Tammy has the
brain hooked up to her computer and video camera and does erotic
dancing for this bodyless version of Michael, unto a sort of electrical
orgasm.
